High-efficient transient expression for customer service (HEK293F, CHO transient expression service)

Y-biologics has optimized protein transient expression system using animal cells (CHO, HEK293) in short period with best quality for providing proteins to our customers.

  • 1Transient Protein Expression Services
    • To reduce our customers’ research time, we perform the pilot expression test (small scale) within 2 weeks and provide all amount of protein to the customer.
    • Under the customer’s request, we provide best quality protein in short period using large scale culture (1L~18L).
    • For the high-purity protein (>95%), we use FPLC and HPLC.
  • 2Culture Size
    • Y-Biologics has small scale (40~100ml) and large-scale(1L~18L) protein expression service.
    • For our customers, 100ml~1L culture is also available.
